NSA policy is very explicit in stating that if they come across evidence of domestic criminal activity in the pursuit of foreign intel, they are free to share that with law enforcement. Given that tracking money laundering is a key approach to attacking terrorism, it's certainly possible that information related to this arrest could arise from that activity. So while its most likely that this went through a subpoena, it's absolutely not conspiratorial to suggest NSA involvement.
